摘要
Abstract
[Objectives] As bolts and pins are important connector for installation of shipboard equipments,using properly simplified method for anti-shock evaluation can reduce the computation cost and improve the simulation efficiency .[Methods] On the basis of time domain analysis on the anti-shock property of shipboard equipment,a marine generator with a large amount of connectors(e.g. boltss and pins) is chosen as research object. Firstly,installation simulation of connection with bolts and pins is carried out to obtain the stiffness charcteristics in different phases of shock loading using busing unit,and equivalent dynamic model of equipment connection is attained. Then,simulation evaluation is made on the marine generator by time domain analysis,the results are compared with experimental data acquired from floating shock platform in order to verify the effectiveness and reliability of the simplified method. Lastly, criteria for failure evaluation of large-scale equipment connection under shock loading is attained. [Results] The deviation of obtained base loads as well as dynamic response between numerical values and experimental data is less than 10%,and the simplified simulation method for connection evaluation process is effective and reliable.[Conclusions] The findings in this paper can provide significant references for the evaluation of the anti-shock properties of equipment.关键词
